Mesa Boogie TT800 hum

Correct.

Until the structure burns down and the insurance company investigating the incident discover the illegal work, deny the claim, and in some extreme cases, file charges against the (now-un-) insured owner.

Standard answer: “ that’s how I bought it”

The most common causes of current (and this voltage drop) on the grounding conductor is reversing the ground and neutral on a receptacle, installing a jumper on an ungrounded branch circuit from the neutral to ground and illegal bonding of neutral to ground on a sub panel.

Common causes? Who the hell would do any of those things (though I suppose the last two might save a buck)? Isn’t someone who does putting their license at risk?

PS - I see you answered this some time ago. ...not always a license involved.

Exactly what “defective product issue” about a Subway amp are you talking about? You need to back your claim up with facts, which I know with 100% confidence you can not.

With every product by every manufacturer there will be an occasional defective amp. This is why manufacturers have warranties. We cover our amps for 5 years, as long or longer than any other manufacturer, and we support our amps for as long as parts are available (we are still supporting amps that are 40+ years old at the factory).

What exactly is your problem with either me or is?

Every forum must have a troll. So it is written.

Just living in reality, other amp manufacturers don't have the same issues as Mesa does and they don't charge a premium.

I understand Mesa has a bottom line but it is just wrong to sell a defective product.

now you are revealed as a troll. No data, no verifiable reference ... I'll call B.S.

As someone looking to potentially buy one of the subway amps (leaning towards the WD800), it is kind of reassuring when someone makes a wild claim like that and then just disappears when confronted about it, especially when confronted by the designer. I'm looking forward to being able to go into a store to try some out in the next couple of weeks now that we have retailers reopening as of today.

@PullThePlug also seemed to be horrified in another Mesa Subway related forum post, that Mesa's excellent 5 year warranty did not cover damage caused by a user dropping their Subway

such d-baggery is so stupid .... and totally transparent. No one would suggest Mesa, or any manufacturer, is perfect and no products ever have an issue, but the data available would suggest that Mesa is a pretty stand up company .... and we here on TB recognize that Mesa certainly goes beyond the call of duty in being present and supportive on this forum.

Oh, I think I remember that one. If I did pull it off my amp, Mesa would repair it, on my dime of course, but it would be a fair price. There are other companies out there that sell their product and will sorta support their warranty if they have to, but after the warranty is over, good luck. Mesa has a phenomenal track record.

Did he pull the amp off a cab? I've always been curious if that is something that happens with a lot of the new smaller amps now that they are lightweight. In your experience, is that much of a risk with the subway series amps? The only amps I've ever gigged were pretty heavy so this was never a worry (M6 Carbine, GK700RB, Eden WT800).

Yes, it's probably the most common cause of damage to the small, light weight amps by all manufacturers. We even have a program where we split the cost of repair the first time it happens, but there are a few customers who are frequent fliers. For them, perhaps they would be better off with a heavier amp.

It's like some folks are better off with a wall mounted landline phone if they are constantly damaging their mobile phones... it's not the phone's fault.

Yeah I could definitely see that with some of the really small amps like those micro gk amps. Wasn't sure if the subways are as prone. They do look like they're more sturdy still than the really small ones. I'd probably spring for the rack kit for the Wd800 if I get it.

Love your sig!….

Thanks! My nephew drew it as a surprise for me several years ago.

I loop my cord through my speaker cabinet handle.
Been doing that BCD (before class D) to keep from pulling my cable out. Now it also helps to keep the head on

What’s your criteria got “bad electrical “?
Just a note- a plug in outlet tester is a handy device, but it doesn’t tell the whole story.

After using a plug-in outlet tester, I use a non-contact voltage tester to see if the ground is hot. As a final test, I ask a sweaty guitar-playing vocalist to touch the microphone with his lips.

It's not how "sturdy" an amp is, but how it hits the ground. Sometimes you are lucky but sometimes you aren't.

What people forget is that when the big, heavy amps do take a fall, often the damage is extensive and expensive.

Ground is “hot” with respect to ?
Where is the potential difference.
Also, shock at the mic is often due to a polarity difference between the PA circuit and the guitar amp.

I'm no electrician but I find a lot of reversed "hot" and "neutral" in the craptastic bars I've played,hehe

 

[agedhorse]

Reversed hot and neutral will not cause problems with these amps.

True, by sturdy I just mean more in terms of actual weight. Like one of those 2 lb amps I wouldn't feel to safe about just leaving unsecured on top of an amp.

I've been fortunate to have never dropped any amps. The worst I've done is leave my 700rb in a parking lot for a good 40 minutes. Took me a while after getting home to realize I forgot to put it in the car but luckily it was still just sitting there next to where my car was parked.

Closing this. OP got their resolution. Trolls, well, a troll ruins threads. An amps mod can clean and reopen if they like.
